Prenatal nicotine affects catecholamine gene expression in newborn rat carotid body and petrosal ganglion.
Nicotine exposure modifies the expression of catecholamine and opioid neurotransmitter systems involved in attenuation of hypoxic chemosensitivity. We used in situ hybridization histochemistry to determine the effect of prenatal and early postnatal nicotine exposure on tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DbetaH), preproenkephalin (PPE), and D2-dopamine receptor mRNA levels in ...
متن کاملThe effect of prenatal nicotine exposure on biphasic hypoxic ventilatory response and protein kinase C (PKC) expression in caudal brainstem of developing rats
Current evidence suggests that maternal smoking is associated with decreased respiratory drive and blunted hypoxic ventilatory response (HVR) in the newborn. The effect of prenatal nicotine exposure on overall changes in HVR has been studied; however, there is limited data on the effect of nicotine exposure on each component of biphasic HVR. To examine this issue, 5day timed pregnant Sprague-Da...

متن کاملCannabinoid receptor expression in peripheral arterial chemoreceptors during postnatal development.
Prenatal exposure to tobacco smoke increases risk of sudden infant death syndrome (SIDS). Marijuana is frequently smoked in conjunction with tobacco, and perinatal exposure to marijuana is associated with increased incidence of SIDS. Abnormalities in peripheral arterial chemoreceptor responses during sleep may be operative in infants at risk for SIDS, and nicotine exposure adversely affects per...
متن کاملP-105: Prenatal Effects Exposure to Extremely Low Frequency- Electromagnetic Field (ELF-EMF) on Pathology of Testis in Newborn Rats
Background: Human beings are unavoidably exposed to ambient electromagnetic fields (EMF) generated from various electrical devices and from power transmission lines. The effects of extremely low-frequency electromagnetic fields (ELF-EMF) on the biological functions of living organisms represent an emerging area of interest for human health. One of the critical issues is that EMF may adversely a...
